The apparatus comprises a base portion ( 2 ) and at least two arms ( 1 ) resiliently cantilevered from the base portion ( 2 ), the inner ends of the arms ( 1 ) forming a button-like member ( 4 ) and each having a projection ( 4 A) for engaging on the outwardly facing surface of a compact disk ( 10 ) held on the apparatus. Depression of the button-like member ( 4 ) causes the projections ( 4 A) to move towards each other until their engagement on the disk ( 10 ) is released. An upstand ( 6 ) surrounds the disk ( 10 ) and is positioned close thereto so as to restrict movement of the disk ( 10 ) within its own plane. The inner ends ( 4 ) of the arms ( 1 ) may be shaped to reduce the risk of forces applied thereto in the plane of the disk ( 10 ) causing the disk ( 10 ) to be released. Finger recesses ( 6 A) in the upstand may be formed so as to inhibit access to the edge of a disk ( 10 ) whilst held by the apparatus but provide access thereto once the disk ( 10 ) has been released. 3-arm release mechanisms are also described.
